Mainland Brazil's Last Volcano? Pico do Cabugi

Описание: Located near the easternmost tip of Brazil is a black mountain often referred to as "the best preserved volcano in Brazil". Known as Pico do Cabugi, it rises 430 meters or 1,410 feet above the surrounding landscape with a profile somewhat similar to an eroded cinder cone. But, is this feature actually an ancient volcano? This video will answer that question and discuss how magma formed its rocky edifice approximately 25 million years ago.
